    • A multi-hop wireless, for example cellular, communications system is provided comprising a source equipment which may be one of a base station or an end user terminal for transmitting signals towards a destination equipment which may be the other of a base station or an end user terminal via at least one relay equipment. The relay equipment receives a plurality of signals transmitted from one or more source equipments of the system and from this plurality of signals selects a signal to relay. In this way the decision about which relays are included in which communication paths in the system is distributed to the relay equipments of the system, thus reducing the signalling overhead as compared with link state protocols which are typically used for routing in such multi-hop systems.

    • A base station in a wireless communications system defines a plurality of beams which each have an amount of resources for supporting communication links with terminals. A control entity determines if a direct communication link can be supported between a new terminal and a base station using a first beam. If a direct communication link cannot be supported, a relaying equipment is used to provide a multi-hop path between the base station and the terminal. The multi-hop path comprises a link between the base station and the relaying equipment using resources of a different beam. This helps to redistribute load within the cell. The direct communication link can be refused if there are insufficient resources in the first beam, or if accepting the new terminal would cause quality of communication links with existing terminals to deteriorate.
    • 无线通信系统中的基站定义多个波束,每个波束具有用于支持与终端的通信链路的资源量。 控制实体确定在新终端和使用第一波束的基站之间是否可以支持直接通信链路。 如果不能支持直接通信链路,则使用中继设备在基站和终端之间提供多跳路径。 多跳路径包括使用不同波束的资源的基站和中继设备之间的链路。 这有助于重新分配单元内的负载。 如果第一光束中的资源不足,或者接受新终端会导致与现有终端的通信链路的质量恶化,则可以拒绝直接通信链路。

    • Spatial Division Multiple Access (SDMA) offers multiplicative spectral efficiency gains in wireless networks. An adaptive SDMA beamforming technique is capable of increasing the traffic throughput of a sector, as compared to a conventional tri-cellular arrangement, by between 4 and 7 times, depending on the environment. This system uses an averaged covariance matrix of the uplink signals received at the antenna array to deduce the downlink beamforming solution, and is equally applicable to Frequency Division Duplex (FDD) and Time Division Duplex (TDD) systems. A scheduling algorithm enhances the SDMA system performance by advantageously selecting the users to be co-scheduled.
    • 空分多址(SDMA)在无线网络中提供乘法频谱效率增益。 根据环境,自适应SDMA波束形成技术能够将传统的三蜂窝布置的扇区的业务吞吐量提高4到7倍。 该系统使用在天线阵列处接收的上行链路信号的平均协方差矩阵来推导下行链路波束形成解,并且同样适用于频分双工(FDD)和时分双工(TDD)系统。 调度算法通过有利地选择要共同调度的用户来增强SDMA系统的性能。

    • A communication system includes base stations having an antenna arrangement per sector. Each of the antenna arrangements has an antenna element for generating an array of narrow beams covering the sector. Timeslots are simultaneously transmitted over each beam to generate successive sets of simultaneously transmitted timeslots per sector that are each split into orthogonal codes. Common overhead channels are allocated for successive sets of timeslots, which are allocated to the same subset of codes of each timeslot in the set. For successive sets of timeslots, different data is allocated to the same subset of codes of each timeslot in the set. This generates a sector-wide beam carrying the common overhead channels and a plurality of narrow beams, each carrying different data. An inter-beam handoff scheme allows the antenna arrangement to simultaneously transmits data to a user equipment located in a cusp region between adjacent beams on the adjacent beams.
    • 通信系统包括每个扇区具有天线布置的基站。 每个天线装置具有用于产生覆盖扇区的窄波束阵列的天线元件。 时隙同时在每个波束上传输,以产生每个扇区的连续的同时发射的时隙集合,每个时隙被分成正交码。 为连续的时隙集合分配公共开销信道,这些时隙被分配给集合中每个时隙的相同的代码子集。 对于连续的时隙集合,不同的数据被分配给集合中每个时隙的相同的代码子集。 这产生了承载共同开销信道的扇区宽波束和多个窄波束,每个窄波束携带不同的数据。 波束间切换方案允许天线布置同时向位于相邻波束上的相邻波束之间的尖端区域中的用户设备发送数据。
